BICYCLE-BRAKE.

SPECIFICATION forming part of Letters Patent NO. 613,965, dated November8, 1898. Application filed May 8, 1897. erial No. 685,711. (No model) Toall whom it may concern.-

Be it known that I, GEORGE FREDERICK CADDEN, a subject of the Queen ofGreat Britain, and a resident of Coventry, in the county of Warwick,England, have invented certain new and useful Improvements in Brakes forVeloeipedes and Vehicles, of which the following is a full, clear, andexact specification.

This invention relates to improvements in brakes for velocipedes, theobject being to simplify the construction of the brake and at the sametime conceal the working parts from view, which are carried in thehollow tube carrying the forks in which the front wheel has itsbearings.

In order that my invention may be fully understood, I will now refer tothe annexed drawing, in which the figure is a sectional front elevationshowing my brake attached to a velooipede. g

a is the brake-surface, which is carried in the piece I), which ismovably attached to the hollow tube 0, having a screw-thread upon sameand which engages in the socket-piece e.

f is a rod of square or other suitable section,

which engages in the tube, which is provided with a socket g of similarsection.

it is a thumb-piece or wheel secured to the top of the rod f, so that onrotating same the brake-surface is caused to engage upon the tire of thewheel '11.

j is a disk or shoulder upon the rod f and which maintains same inposition, rotating between the screwed cap 70, and the bearing Z isformed at or about the middle of the handlebar at the top of the frontfork.

One great advantage of this brake is that in the event of the tirebecoming deflated through being punctured the brake maybe powerfullyapplied, and thus prevent an acci dent when riding downhill, as in thelever- I brakes now commonly used the brake-surface has not sufficientmovement to enable it to engage with the tire in the event of itsbecomin g deflated.

Having thus described myinvention, what I claim, and desire to secure byLetters Pat'- ent, is*

In brakes for velocipedes of the class herein described in combination;a screw-threaded bar inserted in the lower end of the stem; atscrew-threaded metal support carrying on itsunder surface a brake-shoewhich bears upon the tire, and having at its upper end a plug which issquare inserted therein into which fits a square rod which rotates thesaid screwed metal support being adapted to slide freely within thesquare plug g when the handles are adjusted to diiferent heights.

In testimony that I claim the foregoing I have hereunto set my hand this20th day of January, 1897.

GEORGE FREDERICK CADDEN.
